PRESSING-ROLLER.

Specification of Letters Patent.

Patented Nov. 3, 1908.

Application filed August 24, 1906. Serial No. 331,881.

New Jersey, have invented certain new and useful Improvements in Pressing-Rollers, of which the following is a specification, reference being had therein to the accompanying drawings, forming a part thereof.

My invention relates to rollers such as are employed for fiuting or crimping or pressing fabrics and fibrous material, and has for its objects simplicity and economy of construc- I tion, the avoidance of any strams from unequal expansion and contraction of the parts, and i. creased. eil'iciency of operation.

, ther objects of my invention will appear from the following description.

I will now describe the apparatus embody ing my invention illustrated in the accompa nying drawings and will thereafter point out my invention in claims.

Figure 1 1s a vertical longitudinal central section showing a pair of rollers, a frame and bearings for the rollers and means for heating the rollers. Fig. 2 is a longitudinal central section of one of the rollers. Fig. 3 is a crossscci-ion of the roller taken on a plane indicatcd by the line 3-3, in Fig. 2. Fig. 4 is a cross-sectional View of the roller taken on a plane indicated. by the line 44, Fig. 2.

' The two rollers shown in Fig. l are of identical construction except that the lower roller is extended to carry a motion receiving gear 30. This lower roller is separately shown in Figs. 2, 3 and 4. Each roller is made up of two parts, an outer tubular part I 1 and an inner supporting part or core 2.

The outer part 1 is a cylindrical seamless tubc, preferably of brass, and is rigidly secured upon the middle portion of the core in the m annor hereinafter described. The core is preferably of cast iron and is provided with journals and 4. at its ends.

A seriesof ports or openings through the;

core is provided between the journals of the core so ,that this part of the core is a grated frame 01 grid with air supply ports for aifordiiig a proper air sup d y to the heating flames l and flame openings to permit direct action by,

the flames upon the inner surface of the outer As shown, there are four sets of holes, of which the two end sets 6, 6, located in proximity to the 'ournals, are the air supply ports, and the ot or two sets 5, externally covered by the outer tube,

1 are the flame openings for direct access of the flames to the tube. The-air supply ports serve also as a means for keeping down the temperature of the journals. The provision of these ports and openings leaves the struc-.

ture of the core about these openings in the form of a grid composed of four longitudinal bars and three annular bars or rings. These annular rings 7 are of slightly larger diameter than the portion having the longitudinal bars, and one of them, shown as the end ring to the right in Figs. 1 and 2, is turned down.

to a diameter minutely in excess of the inner diameter of the tube 2 so that the tube must be heated to permit it to be passed .over this ring. The other two rings 7 are turned down to a diameter minutely less than the inner diameter of the tube 2 so that the tube loose fit thereon.

In assembling the parts it is necessary to heat the end of the tube which is to slip over the end ring of larger diameter, and upon the cooling of the parts, the tube will beheld by a shrinkage fit. To furupon this ring t1 f ns ring ther rigidly secure the tube upon dially through the tube and core. VVhile the tube is thus rigidly secured to one of the rings 7 it other rings 7 and may therefore freely expand and contract under the varying conditions of heat imparted to it in use and the and the unequal expansion and contraction .of the tube and core will not cause any strain upon either part.

In the manufacture of the roller the journals 3 and 4 may first be turned, the tube 2 then shrunk and pinned upon the core, and if the roller is to be provided with grooves or fluti'ngs, the grooves or flutings may then be cut in the tube. The tube, being of drawn metal, will be free from blow holes or other inherent concealed defects such as are frequent in cast parts and would re uire the entire roller to be discarded when disclosed in cutting the grooves or flutings.

The journals 3 and 4 are shown in Fig. 1 as arranged to rotate in brasses or journalboxes 9 and 10 of usual construction, held in vertical slots or openings formed in'the edestals 11 and 12. The u per 'journaloxes 9 are pressed downward y the helical springs 13 bearing upon the tops of the'bcxes and having their tension regulated by setwill slip o er these two rings and will have a '1 larger diameter, a lock-pin 8 is inserted te is only loosely fitted upon the core may also freely expand and contract screws 14., Which are-"screwed into the bars A flue casting 16 is secured to the pedestal 11 and is provided withbosses 17, the axes of which are coincident with the respective axes of the hollow rollers. The bosses serve as supports for central pipes 18 which extend inward horizontally-from their outer connections with the cylindrical cap 19. This cap is closed at its upper end and provided at its lower end with a bore 20 of smaller diameter than that of the chamber of the cap and into which the fuel feed-pipe 21- fits. The" lower portion of this cylindrical cap is provided with a draft or air inlet 22 thro'ugh which air is drawn by the fuel, thus making a Bunsen burner. The horizontal pipes 18 extend into the hollow rollers and are closed at their ends, and are provided on their upper portions with burner apertures 23.

. To provide means of escape for the heat and gases resulting from the combustion of the fuel supplied by the pipes to the burners just mentioned, the bores ofthe roller jour-- nals 3 adjacent to the casting 16. open into the vertical passage of the casting. The-top ortion 24 of thispassage is threaded and into it is fitted a vertical pipe 25 carrying'ti-ie heated gasesupward and away from the operator. The heat as it passes towards the flue causes fresh-air to be drawn through openings of the journals at the-right hand ends of the hollow rollers, creating a draft thereby, and also causes fresh air to be drawn through the ports or openings 6 in proximity to the ends of the tubes 1.

It is obvious that various modifications may be made in the construction shown and scares above particularly described within the principle and scope of my invention.

I claim as my invention:

1. A pressing roller comprising a hollow core and a tube forming the working surface of the roll, mounted on the core and fittingit tightly for a short part of its length and loosely for the rest of its length.

2. A, pressing roller comprising a hollow core having a plurality of bearmg rings, and

inner surface of the tube to support the same.

el. A pressing roller comprising a tube forming the working surface of the roller, and a core consisting of a grid of less diameter than the tube and a plurality of bearing rings of greater diameter than the grid, one I of said'rings fitting the tube tightly and the others loosely. I

5. A pressing roller comprising a tube of refractory. material forming the working srirface of the roller, and a hollow core, on which the tube 18 mounted, fitting the tube tightly at only a limited part of the length thereof.

and having open ends projerting beyond the ends of the tube to form journals.

in testimony whereof .i have aliixedmy signature in presence of two witnesses.
